Geometric Smocking uses only two stitches, the Cable Stitch and the Trellis Stitch. With these two stitches, you can make thousands of beautiful smocking designs. For example, here is a simple border of hearts and circles, worked in two rows of smocking :

To add a little detail to the diesign, you can stitch a Six-Cable Flowerette in the center of each heart.

In smocking plates, geometric designs are not usually portrayed like this, showing the valleys between the pleats. The most common convention for graphing a geometric represents the top of each pleat with a line, a Cable Stitch with a little "U", and a Trellis Stitch with a little "S". This is how the previous design would be charted :

Another way used to chart a geometric design, although less common, is to represent both Cable Stitches and Trellis Stitches as straight lines. When a slanted line covers more than two pleats, you stitch a Trellis Stitch for each pleat:
